Selling my GM Performance Parts system b/c I upgraded to the Corsa cat-back. It was used for a little over 1,300 miles / 7 months. Fits 2010, 2011, 2012 Camaros with the LS3 V8 and ground effects. GM part # 92225672. Equivalent to Borla's Touring system, from what I hear it's even made by Borla. Moderate street-legal sound, much better than stock but not aggressive like Flowmaster AMT. Original clamps included, mufflers are in excellent condition.
